WebDescription. A conserved series of molecular signals found in prokaryotes and eukaryotes; involves autophosphorylation of a histidine kinase and the transfer of the phosphate group to an aspartate that then acts as a phospho-donor to response regulator proteins. Synonyms. histidyl-aspartyl phosphorelay, phosphorelay signal transduction system. WebJan 1, 1999 · Abstract His-Asp phosphorelays are evolutionary-conserved powerful biological tactics for intracellular signal transduction. Such a phosphorelay is generally made up of “sensor histidine (His)-kinases”, “response regulators”, and “histidine-containing (HPt) phosphotransmitters”.
